DOUBLE-ACTING PUMP.

SPECIFICATION forming part of Letters Patent No. 482,692, dated September 13, 1892. Application filed October 7. 1891. Serial No. 408.029. (No model.)

To aZZ wiz/m, t may concern:

Be it known that I, GEORGE J. NETH, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Double-Acting Pumps, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figurel represents a vertical sectional view, partly in side elevation, of my improved pump; Figs. 2, 3, and 4, detail views hereinafter described.

This invention relates to double-acting force-pumps wherein both the upward and downward strokes of the plunger are utilized to force the water up through the supply-pipe, thereby obtaining a continuous stream during `the operation of the pumps; and its objects "and advantages fully appear in the course of the specification.

Referring to the drawings, d designates the base-plate, suitably supported upon the wellplatform and provided with upwardlyextend ing tubular extensions a a', in which are tapped set-screws a a. The supplyepipe b of the pump passes up through one of these extensions and is supported therein by the set-screw, and the air-chamber tube c passes up through the other extension and is similarly supported, this arrangement permitting vertical adjustment ot said pipes. The spout on the upper end of thesupply-pipe is formed tapering at its discharge end, as at b, and provided on its exterior with annular grooves for the reception of suitable packing. Fitted snugly upon the conical end b is a similarlyshaped conical part b2, which is adapted to be attached to a hose and which is securely held in place by a yoke b3, provided with a thumbscrew b4. The yoke is pivoted on the upper end of the part b2 and swings up over a lug b5, formed on the spout, where it is secured by the setserew, this screw serving to draw the part b2 tightly upon the conical nozzle and form a Water-tight joint therewith. The pipe b is connected to the lower end of the airchamber c at asuitable point below the wellplatform by an inclined tubular casting c 5o which establishes communication between the two tubes. The lower end of the air-chamber is provided with a dischargecock d, which is operated by a rod extending to the well-platform, whereby the water and sediment accum ulated in the same maybe discharged. Upon 5 5 the upper end ot' the air-tube c is screwed a cap provided with another cock d to let the air out of the air-tube whenever desired. The pump-lever f is pivoted between ears formed on the upper end of the air-chamber, the sup- 6o porting-pivots consisting of pointed screws e, tapped into the ears and entering recesses in the lever, whereby wear of the parts may be readily compensated for and the friction reduced to a minimum. Lock-nuts e' are 65 screwed on these screws and bear against the supporting-ears, whereby the screws are prevented from prematurely loosening. The pump-rod f is pivotally secured to the shorter arm of the lever by means of similar screws 7o and lock-nuts for similar purposes. The pump-rod passes down through an opening in the baseplate,between the pipes b c, and has inserted in it a loop or link f", which embraces the inclined connecting-tube c. The pump-rod is provided at its lower end with a piston g', of any desired construction, which works in the cylinder g, the rod passing through a stufiing-box in the upper head g2 of the cylinder.- The lower end of the cyl- 8o inder is closed by a head g, which is provided with an inwardly-opening valve g4. The two longitudinal valvechambers g(i gG are formed integrally with the cylinder, upon opposite sides of the same, and are closed by removable plates 71, whereby ready access may be had to them. The right-hand valvechamber is provided with an inwardly-opening valve Q7 over an opening in its lower end and has its upper end in communication with go the upper end ot' the cylinder. The other valve-chamber has both its ends in communication with the cylinder and is provided with inwardly-opening valves g8 gg, secured over openings in suitable horizontal partitions formed in the chamber. Formed integrally with the left-hand plate h and communicating at its lower end with the interior of the adjacent chamber is a vertical tube 197, into whose upper end is screwed the waterpipe b. roc The lower head g3 of the cylinder has formed integrally with it a depending tube ,which communicates with the Valve-opening in the lower end of the right valve-chamber by a branch passage g5 and which has its lower open end formed into a downwardly-tapering portion i'. This conical part t' rests snugly in a conical socket t", secured upon the upper end of the stationary suction-pipe, a watertight joint being formed between the cone and its socket by annular packing-strips let into grooves on the exterior of the cone. The suction-pipe and socket may be supported in the well by any suitable means-such, for instance, as a bar i2.

A stop-cock h6 may be screwed in the supply-pipe b near its lower end to discharge the water remaining therein after each operation and prevent it freezing in the pipe, this cock peing operated by a rod extending to the plat- To assist -in supporting the cylinder and valve-chambers, a rod c2 connects them to the tubular connection c', the lower end of the rod being attached to an ear formed on the right-hand valve-chamber.

The operation of this pump is evident. Upon the upward stroke of the piston fresh water is sucked up through valve g4 and the water above the piston is forced out through the left valve-chamber and valve g8 and up the supply-pipe, while during the downward stroke water is sucked up through passage g5 and valve g7 into the right valve-chamber and the upper part of the cylinder and is forced out through valve g9 up the supply-pipe, as is evident.

As will be observed, the pump rests in and is partially supported by the stationary conical socket on the upper end of the suctionpipe, whereby in removing the pump for repairs and cleaning it may be readily lifted out of the well without disturbing the suctionpipe or its socket. The vertical adj ustability of the pump enables it to be properly adjustcd so as to lit snugly in its socket on the suction-pipe, as is evident. It will be observed that in replacing the pump after cleaning or repairs it is simply necessary to let it down into the well until its lower conical end rests in the socket on the permanent suctionpipe, whereby the use of bolts and other connecting devices are entirely avoided.

It is preferred to incline the air-pipe c upwardly from the main air-tube to the supplypipe, inasmuch as the air-chamber is thereby rendered more effective in assisting in forcing the water out, the inclination being such that the force of the compressed air in the chambers is applied in the direction ofthe flow of the outgoing water-that is, the inclination of the connection causes the compressed air to act under the outgoing column of water. This is particularly advantageous when forcing the water to long distances or to great heights.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

l. In a pump, the combination of a baseplate, a supply pipe supported thereon, a pump-cylinder and valve-chambers connected to the lower end of the supply-pipe, a piston and rod, an air-chamber supported by the base-plate, and a lateral tubular connection c', connecting the supply-pipe at a point between the base-plate and pump-cylinder with the lower end of the air-chamber, said connection inclining downwardly toward the air-chamber, substantially as described.

2. In a pump, the combination,with a wellplatform and a removable pump adjustably depending therefrom, said pump having its inlet-pipe formed into ahollowconetl at its lower end, of a stationary support within the well and astationary suction-pipe supported thereon and carrying a conical cup, this cup being adapted to receive and closely fit the cone when the pump is let down into the well, as and for the purpose described.

3. In a double-acting pump, the combination of a cylinder g, having its ends closed by removable heads g2 and g3, the latter being provided with a valved opening g4, and a suction-pipe depending therefrom, longitudinali* chambers Q6, formed integrally on the exterior of the cylinder, one of these chambers being provided with a valve-opening at its lower end, communicating by a lateral passage g5 with the suction-pipe, and the other 011e being provided With two separated horizontal partitions having each an inwardly-opening valve, side plates h h, removably bolted over the open sides of said chambers, one of these plates having formed integrally with its exterior a vertical passage 57, communicating at its lower end with the chamber between the valved partitions, a supply-pipe, and a piston and piston-rod, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
